PI6ULS5V9515AWEX

Signal Buffers, Repeaters, Splitters Overview

The PI6ULS5V9515AWEX is an I2C Bus/SMBus Repeater manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.3 V to 3.6 V and supports data rates up to 400 kHz. The device features a single channel with one enable input (EN) that controls signal pass-through between Port 0 and Port 1. When the EN pin is high, SCL0 connects to SCL1 and SDA0 connects to SDA1; when low, the repeater is disabled. It is available in MSOP-8 and TDFN2x3-8L packages.

Signal Buffers, Repeaters, Splitters FAQ

What is the function of the EN pin?

The EN pin is an active HIGH enable input. When high, it allows signals to pass between Port 0 and Port 1. When low, the repeater is disabled.

Does this device perform level translation?

No, the PI6ULS5V9515A is a repeater/buffer designed for the same voltage domain (2.3 V to 3.6 V). It does not translate between different voltage levels.

What is the maximum data rate supported?

The device supports I2C and SMBus protocols with a maximum clock frequency of 400 kHz.
